UNITED STATES .P T EN '1 @F HENRY LEWIS KNOL, OF CHICAGO, ILLINOIS,ASSIGNO'R OF ONE-HALF TO ALFRED HAHN, F CHICAGO, ILLINOIS.v

Application led April 21, 1924. Serial No. 708,019.

To all 'whom t may concern:

Be it known that I, HENRY Lnwrs KNoL,

a citizen of the United States, and a resident of the city of Chicago,county of Cook, and State of Illinois, have invented certain new anduseful Improvements in Mops, of which Vmthe following is aspecification.

My invention relates to mops, and esgecially to the type of mop havingmeans thereon for wringing out the mopping part; and the principalobject of the invention is to provide a mop of this type with means forreally wringing the mopping part substantially dry.

In the mops of this type which are on the market the part of the shafton which the mopping' means is mounted and wrung is of the samethickness as the upper or hand engaged part and the entire shaft ormember is usually of wood, thus making it diiiicult during the twistingor wringing of the mopping means upon said large wooden part, andpractically impossible, to wring said mopping means anywheres near dry,since the moist pliable strands of the mopping means cling to theenlarged wooden surface, and prevent complete twisting and wringingthereof. I overcome this defect by reducing the lower part of the shaftin diameter and by making it of metal, preferably by using a thin smoothor polished metal rod around vphich the mopping means can be readilytwisted and substantially wrung entirely dry, since no friction resultsbetween able material of the mopping means.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which,

Fig. 1 is a view of my invention, with the mopping means in moppingposition;

Fig. 2 is a view thereof, showing the mopping means in the elevated andtwisted or wrung position;

Fig. 3 is an enlarged fragmentary view of the operating mechanism;

Fig. 4 is a sectional view on line 4 4 of Fig. 3;

Fig. 5 is a cross sectional view on line 5-5 of Fig. 4; and

the smooth surface of the rod and the pli-4 Fig. G is an enlarged crosssectional view on line (5*6 of Fig. `4.

The preferred form of construction comprises a shaft or main member 10of wood or other suitable material and having a reduced, smooth lowerportion 11, which preferably consists of a smooth thin metallic rodmounted in the upper part 10 yand having a substantially polishedsurface. Mopping means 12, consisting of the usual strands of pliableabsorbent materialT is fastened with its lower end upon the lower end ofrod 11 and with its upper end upon a collar 13, as with ring or wire 14.The collar 13 is slidably mounted on shaft 11 and is preferably providedwith a metallic collar 15 having slots 15 in its upper edge and hooks 16extending into said slots.

yThe operating means for wringing the mopping means 12 includes asprocket wheel 17 with sprockets or teeth 17', which is rotatablymounted on the lower part of shaft 10 and has a collar 18 fastenedthereto which is provided with pins 19 adapted to move in slots 15 andengage and cooperate with hooks 16. Said wheel 17 is held in position onsaid shaft by means of a ring 2() fastened with a pin 21 on said shaftand rod 11, and by a sleeve 22 on said shaft at the opposite side ofring 20.

The means for rotating the sprocket wheel 17 includes a disc or wheel 23having openings 23 adjacent the periphery for engaging sprockets orteeth 17. Said disc is mounted on a bracket 24 engaging sleeve 22 and isrotatably held in position with a bolt 25 passing through disc 23,bracket 24, sleeve 22, shaft 10. and rod 11. holding said elements inassembled position. A hand crank 26 with a suitable handle is fastenedto said disc for rotating the same and operating sprocket wheel 17 totwist the collar 13 and the upper ends of the strands forming themopping means 12.

The exterior surface of rod 11 is smooth and polished, and said moppingmeans will not adhere to this polished surface but will freely twistaround the same, the crank means 26 and connected disc and sprocketwheel are also arranged to provide considerable power thus enablingperson to actually wring the mop substantially dry.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into eect, this is capable of.variation and modification without departing` from the spirit of theinvention. l, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of .suchvariations and modifications as come within the scope of the appendedclaims.

Having described my invention what I claim as new and desire to secureby Letters Patent is:

l. A mop comprising a shaft, a smooth metallic rod of smallercross-section fastened in the lower. part of said shaft, mopping` meansof absorbent material fastened at one end to the lower part of said rod,al notched collar slidably mounted on said rod and fastened to the otherend of said mopping means, operating means mounted on said shaft andprovided with means adapted to engage the notch of said collar forstretching` said mopping` means and for twisting,` and wringing thesame.

2. A mop comprisinga shaft having,` a smooth metallic lower portion,mopping means fixed at one end to the lower part of said metallicportion, a notched collar slidably mounted on said metallic portion andfastened to the other end of said mopping means, a collar rotatablymounted on said metallic portion and provided with pins adapted toengage the notches of said first mentioned collar and rotate the samefor twisting and wringing said mopping means, and handle means to rotatethe second mentioned collar.

3. A mop comprising a shaft with a thin metallic rod on its lower end,mopping' means of absorbent material mounted with one end on the lowerend of said metallic rod and having a collar fastened to its upper end,a sprocket wheel with means to engage said collar and twist said moppingmeans on said rod, and a disc with a handle fastened on its outer faceand with openings therein to receive and actuate the sprockets of saidwheel.

all. A mop comprising` a shaft with a smooth metallic rod fastened inposition in its lower end, mopping` means of absorbent material fastenedat one end to the lower end of said rod and having a notched collar atits upper end slidably mounted on said rod, a sprocket wheel providedwith pins to engage the notches of said collar and twist said moppingmeans, a disc mounted on said shaft and having openings to receive thesprockets of said wheel and rotate the same, and a hand crank fastenedto said disc for operating the mechanism and wringing said mopping,`means dry.

In testimony whereof I have signed my name to this specification.

HENRY LEVIS KNOL.
